From Open Culture, here's The Writing Life of Joyce Carol Oates:
And dig, the Paris Review Interview with Oates:
Productivity is a relative matter. And it’s really insignificant: What is ultimately important is a writer’s strongest books. It may be the case that we all must write many books in order to achieve a few lasting ones — just as a young writer or poet might have to write hundreds of poems before writing his first significant one. Each book as it is written, however, is a completely absorbing experience, and feels always as if it were the work I was born to write.
